It is also possible to remove thepositioning means for the lenses substantially out of the line of visionof the wearer, particularly near the nose bridge, thereby practicallyeliminating the disadvantages and defects above mentioned. The improvedstructure furthermore makes it possible to insert the lenses into theframes without danger of bending or otherwise stressing the frames orthe lenses, and to clamp the lenses and the retainers thereforpositively in place, without any danger of accidental displacement ofthe parts.

In the particular practical embodiment of my invention which isillustrated, the goggles -G comprise the symmetrically shaped lensframes 15 and 16, mounted by means of hinge H, to provide respectiveright and left hand members of said goggles. Secured pivotally by saidhingeH to the frames 15 and 16, are the lens retainers C. Between theframes 15 and 16 and retainers C are the lenses L, all held securely inposition by the fastener F. The frames 15 and 16 are preferably made ofmetal. or any material capable of being formed or shaped to besubstantially L-shaped in cross-section,and yet provide a devicerelatively light in weight and highly resistant to deformation.

On the upper side of the goggles G, the frames 15, 16 have across-section which is substantially rectangular, as seen at 17. Passingaround the ends 18 of the goggles, the angle becomes more obtuse, asviewed at points 19, in order to conform to the contour of the wearersface. Further, proceeding to the portions which seat upon the cheeks ofthe wearer, the angle becomes rapidly acute, see portions 20, for apurpose hereinafter appearing. tially vertical flanges 21 on the framesare curved to provide surface for,psitioni11g the goggles on the face ofthe wearer. The other flanges 22, having the angularities abovedescribed,provide the means for positioning the lenses L with respect tothe eye E of the wearer, and also provide for increasing the wearersrange of vision as described below.

As shown in Figs. 1, 4 and 9, the portions 28, of flanges 21, intendedfor disposition about the bridge of the wearers nose N, are curvedconcavely outwardly. This formation is necessary since the new hingeconstruction H brings the inner ends of the goggles so close togetherthat said goggles could not otherwise be fitted properly to the nose ofthe wearer.

It will be clear from Figs. 1, 2, 9, and 11 that the frames 15 and 16are curved longitudinally and also transversely from top to bottom asseen in Figs. 2 and 11, to fit the forehead and cheeks. Said transversecurvature is such that the upper portion of the frame, when the latteris worn, will be The upright substanarranged considerably forward of andoverhang the lower portion of said frame. By this arrangement, when thegoggles are worn, the focal center of the lenses L, instead of being ina horizontal line drawn from the center of each lens will be in a lineextending upwardly at an angle to the horizontal. This, as shown in Fig.2, would coincide with the focal center of the eye E.

The portions 20 of the frames 15, 16, particularly approaching thebridge portions 23, are, as previously described, not disposedhorizontally or approximately so, butare given a decided inclinationdownwardly from rear to front, providing sufficient spacing for the.angement on the frame of the shoulders or lens positioning means 24:,which, together with lens retainers C, perform the retaining functionsof a bezel. Said shoulders are so mounted as to eliminate interferencewith the wearers range of vision as much as is'possible and may comprisea member approximately L- shaped in cross-section, one leg 25 thereofbeing secured to the portions 17, 19, 20 in any suitable manner, as bymeans of solder or the like, while the other leg 26 is arranged toproject away from the leg 25 on the portions 17,- 19, 20, at such anangle as to provide a ii-shaped groove 2'? of suitable size to receivethe peripheral portions of the lenses L which generally have bevellededge portions, as shown, against which the lens retainers C abut.

It will be seen from the drawings that the lenses L do not seat entirelywithin the \f-shaped groove 27. A surface of the lens L, so contactswith shoulder 2%, as to constitute a spring bearing for said lens.

As leg 26 approaches the br dge portions 23, its height is materiallyreduced in order to reduce the amount of material ohstructing thewearers vision in a-downward direction. It will be noted (Figs. 2, 9 and11) that, by reason of the downward inclination of the portions 20 ofthe frames 15, 16., near the bridge portions 23, grooves of the properdepth and shape are provided between the shoulders 24 and portions 20,even though the upwardly projecting 26 are almost entirely removed atthese points. lnrzeaed removal of material, of course, is preferable inorder to increase the range of vision.

In order to further clear the line of vision of obstructions in thevicinity of the bridge, frames 15, 16, are brought together closer thanhas been possible heretofore by providing the hinge construction l-l,made up as hereinafter described. Said construction comprises a pair ofspaced hinge cylinders 28 on one frame 16, and a single interme diatehinge cylinder 29 on the other frame member. Said cylinders may beformed in tegral with said frames, shown in lli 3 and 4, or may besecured to said frames in any other convenient manner as by partiallyforming some integral with the frames and soldering others thereto. Thehinge pintle is passed through said cylinders to aline them and retainthe frames 15, 16 in operative relation with respect to each other, thecylinder 29 substantially filling the space between the cylinders 28,whereby the frame members are free to swing about the pintle 3Orelatively to each other with minimum necessary play.

Lens retainers C made up in a manner to present a flanged outerperiphery shaped to conform to the contour of frames 15, 16 are hingedlymounted on each of said frames and serve to maintain the lenses Lreinovably in place. The ends 31 of the retainers C ad- 3' acent thehinge cylinders 28, 29, are provided with a pair of spaced hingedcylinders'iji preferably integral with, and if so desired, formed fromthe same sheet of material from which the retainei are made. Hingedcylinders 83 for each of said retainers are secured to frames 15, 16, inan suitable manner. Cylinders 83, as seen in 1-, may be individuallysecured th reto, as by solder or the like. lhe hinge pin S 1 pivotallyse cures the cylinders 82 and 33, together. lit will be seen that, bythe hinge construction just described, the retainer C may be retatedfreely about pin 3%, and as appears from Fig. 3, sufficient space isthereby pro vided for the quick and easy insertion in place in thegroove 2? of the lenses L without bending or straining the parts.

In Fig. 12, is shown a modified hinge construction in which all thehinge cylinders are made integral with the frames or with the lensretainers. ()n one lens frame 5%, the end metal is turned back to formthe alined cylinders 55, 56 between which the cylinder 5? formedsimilarly on the other frame 58 is received. The metal between cylinders55, 56 is turned back to form the hinge cylinder 59 which is mountedbetween the cylinders 60, 61 formed in the same 11 1311 nor on the endof lens retainer ()n the other lens frames, metal por ions on each sideof cylinder 57 are turned back to provide the alined hinge cylinders 63,6 1 for receiving the hin e cylinder 65 formed integral with and at theend of, lens retainer 66.;

Suitable hinge pintles are inserted through the alined hinge cylindersto position the parts for pivotal movement.

At the ends of the retainers G, opposite to that at which the hingestherefor are located, fastening means F for maintaining said retainersremovably, yet securely positioned, on frames l5, 16 are provi ed. Saidlugs include the internally threaded post (Fig. 5) suitably secured tothe frame ends 18, as by soldering or riveting. A lug 36 having aperforation therein extends from the retainer C and maybe made of aseparate piece secured to the retainer or may, if desired, be madeintegral therewith. Said retainers may swing about the hinge pins 84;,so that their flanged peripheries overlap the flanged portions 17, 19and 20 of the frames 15, 16, whereby the l ns periphery isv like, an eyeis suitably secured to the post.

35 in a suitable openingprovided therefor. In Figs. 6, 13 and 14, areshown modified constructions of the lens retaining locking means. In themodification shown in Fig. 6, a portion 43 is struck up from thevertical flange 21 to provide a prong over which is received the slottedextension a l of the lens retainerC. The usual snap fastener or handsfor attaching the goggles to a helmet. or the like, may be securedthrough the opening thus provided. a r

In Figs. 13 and 1 1, a modified fastening means is shown in which acylinder 45 is secured to'the flange 21, said cylinder having an opening46 therethrough. A pin 47having a reduced intermediate portion 1-8 isrotatably positioned in said opening and held against sliding movementby the set screw .19 engaging said reducedportion. The head 50 of saidpin has an eye formed therein, for the purpose of receiving a snapfastener of a band or helmet. The extension 51 of the lens retainer Chas formec. therein the slot 52 through which the head 50 may be passed.Then, by giving the head a half turn, said head and the sides of theslot 52 will act to hold the retainer in locked position. V

A cushion 41 of rubber or other suitable resilient and comparativelysoft material is shaped to conform to the contour of the rear face ofthe goggles. Said cushion may be secured to said goggles by stitching,the stitches being received through perforations (not shown) made inframes 15, 16. Said cushion may be interposed between the goggles andthe face of the wearer to insure a comfortable air tight "and heat tightjoint, and also to prevent the discomfort of contacting metallicsurfaces and edges, and to insure a proper and comfortable fit to thecontour of the face of a wearer, especially on the bridge of the noseand to the cheek portions thereabout. Cushion ll is thickened andwidened at the bridge portion 4-2 hereof, preferably as shown in Figs. 7and 8.

The one operation of molding the rubber cushion with a flat surface 53for contacting the vertical flange 21 and with the thickened portions 42avoids the operation of bulging the metal frame at the bridge portions.

If desired, suitable ventilating means 43* of the Venturi type inducingair circulation in the interior of the goggles and through passages orholes made in the walls of said goggles, may be provided.

It will be seen that there has been provided goggles wherein theobstruction to vision, particularly at and near the bridge of the nose,have been removed to a great degree, that the improved constructionprovides a positive and secure lug for the lens retainers, and a meansfor fitting the various wearers, and that the lenses may be quickly andeasily inserted thereinto and removed therefrom without undue stressingof the arts.

It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved, and which is welladapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention,and as various changes might be made in the embodiment above set forth,it is to be understood that all matter herein set forth or shown in theaccompanying drawing is to be interpreted as illustrative and not in alimiting sense.
